Active clinical trials for "Bile Duct Neoplasms"

The purpose of this study is to evaluate the incidence of complications with the isolated Roux-en-Y reconstruction after pancreaticoduodenectomy in pancreatic tumor and periampullary tumor patients. A prospective randomized controlled trial was conducted to compare the incidence of complications with isolated Roux-en-Y reconstruction with those of Billroth-II-type reconstruction after pancreaticoduodenectomy.

In this randomized trial two two self-expanding metal stents (SEMS) for treatment of malignant biliary strictures are investigated. A newly developed PTFE (Polytetrafluorethylen) (Teflon) stent is tested versus standard covered metal stents. PFTE (Teflon) coating promises improved formability over standard silicone-coated stents, easier removal through the soft surface, and significantly reduced tumor growth through the impermeable surface.

In extrahepatic bile duct cancer and pancreatic cancer, we will treat postoperatively with COX2 inhibitor and assess survival rate and recurrent rate.

The sensitivity of brushing cytology used to distinguish the cause of biliary strictures is low and clinical usefulness is not secured. The aim of this study was to develop a new differential staining method for cytology which is difficult to differentiate by the conventional staining method using biliary cancer related protein expressed only in bile duct cancer.

RATIONALE: Studying samples of blood in the laboratory from patients with cancer and from healthy participants may help doctors identify and learn more about proteins related to cancer. It may also help doctors tell whether a patient has cancer. PURPOSE: This clinical trial is looking at proteins in blood samples to see how well they work in finding pancreatic cancer and extrahepatic biliary tract cancer.

Endoscopic stent insertion is considered the method of choice for palliation of malignant bile duct obstruction (MBDO). However, it can cause complications and requires periodic stent exchanges. While endoscopic stenting is clearly indicated for relief of cholangitis or refractory pruritus, its role in patients with jaundice alone is less clear. Endoscopic stenting for this relative indication might be justified, if there is a significant improvement in quality of life (QOL) of such patients. The aim of the investigators study was to determine whether endoscopic stenting for MBDO results in improved QOL.

The purpose of this prospective, randomized multicenter study is to determine whether there is any difference in stent patency of covered metallic stents in terms of stent positioning, above and across the sphincter of Oddi, in malignant bile duct obstruction.

This registry will collect data from patients routinely undergoing an ERCP and Cellvizio endomicroscopy procedure (and optionally an additional cholangiopancreatoscopy procedure) due to suspected pancreatic or bile duct cancer. The objective is to determine if endomicroscopy images collected using the marketed Cellvizio device may help endoscopists more accurately diagnose, in conjunction with traditional tissue sampling techniques, whether a suspected lesion is malignant or benign.

The primary objective of this study is to assess the safety, tolerability and toxicity of preoperative HBOT in patients undergoing a pancreaticoduodenal resection for premalignant and malignant tumors of the common bile duct, periampullary and duodenum.

The aim of the present prospective study was, first, to verify the correlation between biliary colonization and postoperative infectious complications, and secondarily to asses morbidity and mortality for patients who underwent pancreaticoduodenectomy. The hypothesis is that a proportion of post-operative infections after pancreaticoduodenectomy is due to bacteria that colonize the bile ducts during the preoperative period.
